This paper proposes a wireless power transfer system suitable for unmanned aerial vehicle nests based on the principle of magnetic coupling resonant.The system adopts the series-series resonant network and achieves con-stant power wireless power supply through output power prediction algorithm and output power closed-loop con-trol.Compared with existing wireless power transfer system,there is no need for additional DC-DC converters,and constant power output can be achieved with simple control methods,which reduces the hardware cost and control complexity of the system.Finally,a 20W,887kHz experimental platform is designed.The experimental results verify the effectiveness of the proposed control strategy.
